NEMSIS

What NEMSIS does

NEMSIS (National Emergency Medical Services Information System) is a federally administered Technical Assistance Center that maintains the national data standard and database for emergency medical services in the United States. Headquartered in Salt Lake City, Utah, and operating under the direction of NHTSA's Office of EMS, NEMSIS defines and enforces the Version 3 Data Standard — a specification covering how patient care information resulting from 9-1-1 calls is collected, stored, and transmitted — using data dictionaries, XSD schemas, Schematron validation libraries, and defined lists. The national database aggregates submissions from 13,225 EMS agencies across all 53 U.S. states and territories, processing over 30.5 million Patient Care Reports year-to-date with a fastest data arrival time of seven minutes from record completion.

NEMSIS's core products include the Version 3 Data Standard, software compliance testing and certification services, the annual Public-Release Research Dataset (the largest publicly available EMS dataset in the U.S.), the interactive EMS Data Cube, and a suite of Tableau-based public dashboards covering drug overdose surveillance, heat-related EMS activations, prehospital pediatric quality measures, STEMI care, naloxone administration, motor vehicle crashes, and data quality. Specialized datasets such as the Non-Fatal Opioid Overdose Tracker (developed with the White House ONDCP) and the Violence Against EMS Personnel Dataset (launched April 2026) extend the platform into public health policy and responder safety. Technical resources are hosted on a public Bitbucket repository at git.nemsis.org, with web services supporting Version 3 data submission and retrieval.

The organization is not a commercial entity: it is funded through NHTSA oversight and serves four primary stakeholder groups — state and territorial EMS offices, local EMS agencies and clinicians, EMS software vendors (who must certify compliance), and academic researchers. Datasets and compliance resources are provided at no charge; the TAC operates as a public-good technical assistance center rather than a revenue-generating business, and source data explicitly notes that revenue information is unavailable. Distribution is direct via the nemsis.org portal, bimonthly V3 Implementation Calls, and the annual NEMSIS meeting (2025 in Park City, UT; 2026 scheduled for Heber City, UT).
